Environment sensors are for measuring various parameters of an environment including temperature, humidity, pressure etc. either for indoor or outdoors. This can be indoor applications such as a data center or server room. Also, a major outdoor applicationis monitoring theweather.

Even though there are a huge number of parameters to be measured in the environment, the classification environment sensors hugely refer to temperature and humidity of the atmosphere. Also common environment elements such as Carbon dioxide, Oxygen andCarbon Monoxide are sometimes referred under this category, which is separately detailed by us in our page onGas sensors.

An environment monitoring system is commonly referred to a monitoring system for data centres and server rooms. For these applications, we need to constantly monitor and record various parameters such as temperature, humidity, light, smoke, fire, door opening, power failure, water leakage etc. So this system has to monitor the entire environment inside the data centre or server room. Hence customers commonly refer an environment monitoring system for these applications.

We provide standalone systems which can work even in thecase of a power failure. Normal systems are connected to a server and will not work if there is a network problem, loss of WiFi connection etc. However, our system will continue to work and will provide a phone call and SMS alert even in the case of a total power failure. In the case of escalation of any of the parameters, it will give phone calls to 4 operators and also can deliver a customised recorded voice message.

We provide two versions of the system viz. network connected system and standalone system. The standalone system operates through a SIM card and also can be connected to a battery backup. In both the cases, the customer can remotely view the current parameters over the internet. We can also provide aremote control system to send signals to the data centre to control different actions such as change the temperature setting, switch on a dehumidifier etc.

You may see our model SKU-VAC-ES-154 in this image which are for data centres and server rooms. It can send the data to a cloud server. The user can view the data remotely on any computer or smart phones.

The device has water leak detection sensors as well. You may also see ourseparate device for water leak detectionin server rooms, control rooms, data centre etc. This also can generate aphone call, SMS etc

Sensors for measuring various mechanical parameters are included under this category.

Mechanical parameters being measured by numerous types of mechanical sensors are flow, pressure, acceleration, vibration, movements, torque, axial load, temperature etc. for machinery and other industrial applications. Sensors and actuators are a major part of mechanical sensors There are analogue and digital type of sensors available. Transmitters, Sensors and actuators are often part of a complete solution under this category.

Pressure sensors are one of the most commonly used application under mechanical sensors. Pressure to be monitored include liquid pressure, the mechanical pressure being applied to machine components, pneumatic pressure in hydraulic machinery, barometric pressure, vacuum pressure etc. and are commonly associated with pressure transmitters which are for transmission of the sensor signals to other devices. Pressure gauges are generally analogue devices for displaying the pressure measurement. Nowadays the term pressure gauge is also used for digital displays.

Pressure transmitters are used for process control and automation which will require monitoring, control and coordination between various elements. All such transmitters convert the measured signals into a proportionate electrical voltage and current signals. Many of the models of pressure transmitters have a locally mounted digital display along with the pressure sensor so that the readings are available locally and also is transmitted for centralised monitoring and control.

Differential pressure sensors are used for air, gas etc. to monitor pressure difference between two areas. A typical usage of the same is to monitor pressure difference between special care units in hospitals, critical manufacturing areas etc.

Gas sensors detectvarious atmospheric gases, toxic and nontoxic gases. The chemical content of the gas is also part of the detection process and hence are also known as chemical sensors. Different types of technologies are used to analyze the gas content.
All such sensors are also known as gas detectors and hence the terms are used interchangeably and should not be confused with.Various gas sensors are CO2 sensor, CO sensor, O2 sensor, Hydrogen sensor, Methane (CH4) sensor, LPG (Liquid Petroleum Gas) sensor, Gas leakage sensor, Nitrogen Dioxide (NO2), Hydrogen Sulfide (H2S), Ammonia, Sulfur Dioxide (SO2), Ozone (O3) sensor, Natural Gas (CNG) sensor, Argon detector etc.Different models of portable and fixed type of gas detectors are available for different purposes. Portable sensors are used for industrial and hazardous environments where individuals need to carry them and check the gas levels before entering confined areas, hazardous areas etc. The portable ones are also known as gas detection meters.

Piezoelectric sensor utilises piezoelectric effect to measure mechanical forces such as pressure, vibration etc. Piezoelectric crystals convert mechanical energy into electric energy and vice versa. When a pressure is applied to a piezoelectric crystal, a proportionalelectric voltage is generated. Similarly, when an electrical voltage is applied across the crystal, a proportionate mechanical energy is developed. Piezoelectric sensors are manufactured such piezoelectric crystals. These sensors are generally used to measure sudden mechanical variations, vibrations and fluctuations and these are not suitable for continuous forces. A continuous pressure applied on a crystal will not produce accurate electric signals. For such requirements, a pressure sensor would be ideal.
